All CRS is NAD 83/UTM 19N.  Also ,the acreage discrepancy was within the
same shapefile!

Check you CRS and see that they correspond. That's my first guess because of
the discrepancy in the acreage

Look what the project crs is and make sure the layer has the same

Some are files I created and some are from others.  I can be editing
shapefile and it will crash, sometime but not always when saving. 

 

Here is a more bizarre example:

 

Yesterday I went to add a polygon to an to an existing shapefile that I had
worked on before. The add polygon process looked fine, it shows up in the
attribute table, the calculated acreage is 0.004 acres when it should be 1.4
acres, and all the areas of the other polygons are OK.  When I click zoom to
selected rows from the attribute table it zooms to the entire polygon, but
when I click the polygon on the map with the Information button there is
nothing there.  Then or any time in this process it  may crash.  This is on
a map with some photos as base and a few other layers.   So, I tried an
experiment and opened a new QGIS project, opened the shapefile and was able
to add a polygon with no problem.  Then I closed the new project, opened the
old project, and was able to open the edited polygon and update the
properties, etc.  

 

With another project with some of the same layers I tried to make a new
shapefile layer and went through all the steps, the layer was created, (all
the basic files are visible in Explorer) but I could not actually create a
polygon that was visible.  So, I went to the simple "new  project" (no
rasters) described in the prior paragraph and was able to create a new layer
and create  the polygon I wanted.  Saved that, then I could open it and see
it with the old project.

 

These issues seem to be getting more frequent. Even when I am able to create
shapefiles and edit polygons I may get one to several crashes in a session.

Yes, I use qgis 1.8. I have minor problems but no crashes, and no problems
editing shapefiles.

Did you create the shapefiles in qgis, or did you get them from somewhere
else?

Hi Jake,

 

QGIS  seems to crash a lot for  me when editing shapefiles. I think it is
mostly since I "upgraded" from v1.6 to 1.8.  This is on a vintage 2008 VISTA
machine.   Are you sing QGIS and have you had any problems?
